Hi, i have

“permissions”: [
“storage”
],

in my json, but debug tells me it still cant use the

await browser.storage.local.set({c}).then(setItem, onerror);

Any suggestion? It might work when i load the extension as “new”, but when i reload, it doesnt work.

I am keeping Firefox DevEdition open and just press reload in the temporary extension are.
